Chemical formula C₈ (eight-carbon fragment)
Math index x₈
Large glyph ₈
Semantic note For non-digit subscripts, prefer <sub> (e.g., H2O).

🧠 How It Works

1

Hexadecimal Code

&#x2088; references Unicode 2088 in hexadecimal to produce the glyph ₈ in HTML.

HTML markup
2

Decimal HTML Code

&#8328; uses the decimal code point value 8328 to render the same character.

HTML markup

CSS Entity (Escape)

\2088 is used in CSS (often in content) to generate ₈ in pseudo-elements like ::before and ::after.

CSS stylesheet
=

Same visual result

All methods render ₈. Unicode is U+2088 (Superscripts and Subscripts). There is no named HTML entity for this character.

Use Cases

The subscript eight (₈) commonly appears in the following scenarios:

🧪 Chemistry

Molecular formulas and carbon counts (e.g., C₈ in chain or ring notation).

📐 Math

Indices and sequences like x₈, a₈ in notation.

📋 Footnotes

Compact subscript markers in text-heavy content.

💻 CS / Notation

Base notation like 10₈ for base-8 (octal) examples.

📚 Education

Textbooks and tutorials with simple subscripts.

🎨 Typography

💡 Best Practices

Do

  • Use <sub> when the subscript is a word or phrase
  • Use numeric references (&#x2088; / &#8328;) for portability
  • Keep formula formatting consistent across the page
  • Verify font support for Superscripts/Subscripts when important
  • Consider MathML/MathJax for complex equations

Don’t

  • Mix Unicode subscripts with random <sub> usage without reason
  • Assume every font renders ₈ at the same size and position
  • Use the CSS escape inside HTML content
  • Let line-height collapse around formulas (adjust if needed)
  • Use ₈ where a normal “8” is intended
